## Introduction ##
SeaweedFS is a simple and highly scalable distributed file system. There are two objectives:
1. to store billions of files!
2. to serve the files fast!
SeaweedFS started as an Object Store to handle small files efficiently. Instead of managing all file metadata in a central master, the central master only manages file volumes, and it lets these volume servers manage files and their metadata. This relieves concurrency pressure from the central master and spreads file metadata into volume servers, allowing faster file access (just one disk read operation).
SeaweedFS started as an Object Store to handle small files efficiently. Instead of managing all file metadata in a central master, the central master only manages file volumes, and it lets these volume servers manage files and their metadata. This relieves concurrency pressure from the central master and spreads file metadata into volume servers, allowing faster file access (O(1), usually just one disk read operation).
SeaweedFS can transparently integrate with the cloud. With hot data on local cluster, and warm data on the cloud with O(1) access time, SeaweedFS can achieve both fast local access time and elastic cloud storage capacity, without any client side changes.
There is only 40 bytes of disk storage overhead for each file's metadata. It is so simple with O(1) disk reads that you are welcome to challenge the performance with your actual use cases.
SeaweedFS started by implementing [Facebook's Haystack design paper](http://www.usenix.org/event/osdi10/tech/full_papers/Beaver.pdf).
SeaweedFS started by implementing [Facebook's Haystack design paper](http://www.usenix.org/event/osdi10/tech/full_papers/Beaver.pdf). Also, SeaweedFS implements erasure coding with ideas from [f4: Facebook’s Warm BLOB Storage System](https://www.usenix.org/system/files/conference/osdi14/osdi14-paper-muralidhar.pdf)
SeaweedFS can work very well with just the object store. [[Filer]] can then be added later to support directories and POSIX attributes. Filer is a separate linearly-scalable stateless server with customizable metadata stores, e.g., MySql/Postgres/Redis/Cassandra/LevelDB.
On top of the object store, optional [Filer] can support directories and POSIX attributes. Filer is a separate linearly-scalable stateless server with customizable metadata stores, e.g., MySql, Postgres, Mongodb, Redis, Etcd, Cassandra, LevelDB, MemSql, TiDB, TiKV, CockroachDB, etc.
## Additional Features
* Can choose no replication or different replication levels, rack and data center aware
* Automatic master servers failover - no single point of failure (SPOF)
* Automatic Gzip compression depending on file mime type
* Automatic compaction to reclaim disk space after deletion or update
* Servers in the same cluster can have different disk spaces, file systems, OS etc.
* Adding/Removing servers does **not** cause any data re-balancing
* Optionally fix the orientation for jpeg pictures
* Support Etag, Accept-Range, Last-Modified, etc.
* Support in-memory/leveldb/boltdb/btree mode tuning for memory/performance balance.

## Example Usage ##
## Example Usage
By default, the master node runs on port 9333, and the volume nodes run on port 8080.
Let's start one master node, and two volume nodes on port 8080 and 8081. Ideally, they should be started from different machines. We'll use localhost as an example.
SeaweedFS uses HTTP REST operations to read, write, and delete. The responses are in JSON or JSONP format.

## Architecture ##
Usually distributed file systems split each file into chunks, a central master keeps a mapping of filenames, chunk indices to chunk handles, and also which chunks each chunk server has.
@ -279,12 +327,26 @@ Each individual file size is limited to the volume size.
All file meta information stored on an volume server is readable from memory without disk access. Each file takes just a 16-byte map entry of <64bit key, 32bit offset, 32bit size>. Of course, each map entry has its own space cost for the map. But usually the disk space runs out before the memory does.
### Tiered Storage to the cloud ###
The local volume servers are much faster, while cloud storages have elastic capacity and are actually more cost-efficient if not accessed often (usually free to upload, but relatively costly to access). With the append-only structure and O(1) access time, SeaweedFS can take advantage of both local and cloud storage by offloading the warm data to the cloud.
Usually hot data are fresh and warm data are old. SeaweedFS puts the newly created volumes on local servers, and optionally upload the older volumes on the cloud. If the older data are accessed less often, this literally gives you unlimited capacity with limited local servers, and still fast for new data.
With the O(1) access time, the network latency cost is kept at minimum.
If the hot~warm data is split as 20~80, with 20 servers, you can achieve storage capacity of 100 servers. That's a cost saving of 80%! Or you can repurpose the 80 servers to store new data also, and get 5X storage throughput.

## Compared to Other File Systems ##
Most other distributed file systems seem more complicated than necessary.
SeaweedFS is meant to be fast and simple, in both setup and operation. If you do not understand how it works when you reach here, we've failed! Please raise an issue with any questions or update this file with clarifications.

SeaweedFS can also store extra large files by splitting them into manageable data chunks, and store the file ids of the data chunks into a meta chunk. This is managed by "weed upload/download" tool, and the weed master or volume servers are agnostic about it.

MooseFS chooses to neglect small file issue. From moosefs 3.0 manual, "even a small file will occupy 64KiB plus additionally 4KiB of checksums and 1KiB for the header", because it "was initially designed for keeping large amounts (like several thousands) of very big files"

### Compared to Ceph ###
Ceph can be setup similar to SeaweedFS as a key->blob store. It is much more complicated, with the need to support layers on top of it. [Here is a more detailed comparison](https://github.com/chrislusf/seaweedfs/issues/120)
SeaweedFS has a centralized master group to look up free volumes, while Ceph uses hashing and metadata servers to locate its objects. Having a centralized master makes it easy to code and manage.

## Dev Plan ##
More tools and documentation, on how to maintain and scale the system. For example, how to move volumes, automatically balancing data, how to grow volumes, how to check system status, etc.
Other key features include: Erasure Encoding, JWT security.
This is a super exciting project! And we need helpers and [support](https://www.patreon.com/seaweedfs)!
BTW, We suggest run the code style check script `util/gostd` before you push your branch to remote, it will make SeaweedFS easy to review, maintain and develop:

## Disk Related Topics ##
### Hard Drive Performance ###
When testing read performance on SeaweedFS, it basically becomes a performance test of your hard drive's random read speed. Hard drives usually get 100MB/s~200MB/s.
### Solid State Disk
### Solid State Disk ###
To modify or delete small files, SSD must delete a whole block at a time, and move content in existing blocks to a new block. SSD is fast when brand new, but will get fragmented over time and you have to garbage collect, compacting blocks. SeaweedFS is friendly to SSD since it is append-only. Deletion and compaction are done on volume level in the background, not slowing reading and not causing fragmentation.

## SEAWEEDFS - helm chart (2.x)
### info:
* master/filer/volume are stateful sets with anti-affinity on the hostname,
so your deployment will be spread/HA.
* chart is using memsql(mysql) as the filer backend to enable HA (multiple filer instances)
and backup/HA memsql can provide.
* mysql user/password are created in a k8s secret (secret-seaweedfs-db.yaml) and injected to the filer
with ENV.
* cert config exists and can be enabled, but not been tested.
### current instances config (AIO):
1 instance for each type (master/filer/volume/s3)
instances need node labels:
* sw-volume: true (for volume instance, specific tag)
* sw-backend: true (for all others, as they less resource demanding)
you can update the replicas count for each node type in values.yaml,
need to add more nodes with the corresponding label.
most of the configuration are available through values.yaml

Hi
This PR adds support for building a snap package of seaweedfs. Snaps are cross distro Linux software packages. One snap can be installed on Ubuntu all supported LTS and non LTS releases from 14.04 onward. Additionally they can installed on Debian, Manjaro, Fedora, OpenSUSE and others. Making a snap of seaweedfs enables you to provide automatic updates on your schedule to your users via the snap store.
If accepted, you can use snapcraft locally, a CI system such as travis or circle-ci, or our free build system (build.snapcraft.io) to create snaps and upload to the store (snapcraft.io/store). The store supports
To test this PR locally, I used an Ubuntu 16.04 VM, with the following steps.
```
snap install snapcraft --classic
git clone https://github.com/popey/seaweedfs
cd seaweedfs
git checkout add-snapcraft
snapcraft
```
The generated a .snap file from the tip of master (I could have checked out a stable release instead). It can be installed with:-
snap install seaweedfs_0.99+git30.79371c0-dirty_amd64.snap --dangerous
(the --dangerous is necessary because we’re installing an app which hasn’t gone through the snap store review process)
Once installed, the (namespaced) weed command can be executed. If you accept this and land the snap in the store, we can request an ‘alias’ so users can use the ‘weed’ command rather than the namespaced ‘seaweedfs.weed’
- Run the command
- Create sample config. Snaps are securely confined so their home directory is in a different place
mkdir ~/snap/seaweedfs/current/.seaweedfs
seaweedfs.weed scaffold > ~/snap/seaweed/current/.seaweedfs/filer.toml
- Run a server
seaweedfs.weed server
- Run a benchmark
seaweedfs.weed benchmark
Results from my test run: https://paste.ubuntu.com/p/95Xk8zFQ7w/
If landed, you will need to:-
- Register an account in the snap store https://snapcraft.io/account
- Register the ‘seaweedfs’ name in the store
- snapcraft login
- snapcraft register seaweedfs
- Upload a built snap to the store
- snapcraft push seaweedfs_0.99+git30.79371c0-dirty_amd64.snap --release edge
- Test installing on a clean Ubuntu 16.04 machine
- snap install seaweedfs --edge
The store supports multiple risk levels as “channels” with the edge channel typically used to host the latest build from git master. Stable is where stable releases are pushed. Optionally beta and candidate channels can also be used if needed.
Once you are happy, you can push a stable release to the stable channel, update the store page, and promote the application online (we can help there).

SeaweedFS is a simple and highly scalable distributed file system,
to store and serve billions of files fast!
SeaweedFS implements an object store with O(1) disk seek,
transparent cloud integration, and an optional Filer with POSIX interface,
supporting S3 API, Rack-Aware Erasure Coding for warm storage,
FUSE mount, Hadoop compatible, WebDAV.
